Hiya Squidbreath, I'm RMD.

I'm fairly new, but word on the street is that the workshop board got deleted on account of people making more posts about whether they should post something there, rather than just straight-up posting. Now the case seems to be a person should just post wherever(not specifically wherever, but you seem like a veteran so you know) and whatever crit comes, comes! but anyway

You've got a very interesting and painterly style! It reminds me a lot of someone named Glitchedpuppet, except with acrylcis or some equivalent. What program do you use?

Speaking of painting, was this a speedpaint? I find it interesting how both Scout's and Medic's left hands have been simplified.

Ok but anyway, how to improve. Some points:
-I'm having trouble figuring out the room they are in? I see a stage type of object, but the vertical iron doughnut on the ground is throwing me off, is there some kind of small channel between the stage and the door?
-You made Archimedes a fantail pigeon! Aa! scuse me while I scream in joy. My one quip is that I can't seem to find the beak? So I can't tell if Archimedes is looking up and to the left, or down and to the right. I suppose either one works, but if it was important to the picture, I can't tell.
-Speaking of things I mistook for other things, I thought that Heavy was actually a stylized femscout in a baggy shirt for quite a while, whooops. S'all about conveyance! I'm under the impression that fem heavy is still enormous, but I had a heck of a time trying to both find and install a model of her. I did find a poster someone else (Unithelucario for ref, had trouble uploading picture but it's out there) did, and I'm assuming that they used the standard model. You could probably do well by widening your canvas and widening the shoulders. I went and got down on my hands and knees, and I get the impression that unless Heavy's shoulders are very pushed forward, there should be more clavicle and rib and whatnot there.
-As this is a predominately cool-colored painting, you could probably desaturate the saturated bits of Heavy's shirt even more, it would still look red in proportion to all the blue. Personally though, I think the little bit of warmth in it is nice.
-I think medic looks great tbh, the only things I would fix are those lines over the bottom corner of her coat. I don't know what she's looking at, but I guess it's not important to the picture.

Hope I helped and didn't talk your ear off!

ah its so nice to see other people posting on this board (and f/f content too! excellent!)
I can give you some anatomical critique if you want
Heavy looks smaller than medic, when we all know that heavy's model is much larger

I don't normally do this but I did some red lines to show where you're off. At first I wasn't sure if it's because of the angle you're going for, but your medic's torso is too short. The average female is about 7-7.5 heads tall, whereas yours is only about 6 from the looks of it. The torso should be about 3 heads from the bottom of the chin to the bottom of the pubis. You need to lengthen the torso as well as the arms. I'm not sure if it's the perspective but they look a little short. The elbow should be at belly button level or where the natural waist is, and the tips of the fingers should hit at the upper to mid thigh.

I can't say much for the fem heavy but double check the anatomy just in case to make sure the proportions are right. I like the painterly style you're going for. Technically BLU medic's coat should be less saturated and more of an off-white than a bright blue, but I do like how it makes her appear like she's glowing. I like the expressions and atmosphere you've created. Keep up the good work, you just need to polish it.
