heya, first of all i gotta say i really like this piece, youve done a great job with the atmosphere and the colors. now onto the face: you gotta think of the form of the muzzle and how it affects things you put on it, like the glasses for example, a part of them will be hidden. Also the eye closer to us is a bit too low on the muzzle. you can think of the muzzle as a box, and the lines of a box should always converge atleast a little bit, like you can see on the two drawings on the bottom. now onto the second biggest thing: when you squint you can see that all the values are really close to eachother, which makes the focal point get kinda lost in the background, the easiest fix is just adding more contrast, like for example the horns on their head, i added a shadow on the ground and added more highlights on the horns to really make it pop out, also on the tail you can see how a couple bigger and more contrasting simple shapes describes the texture more visibly. also some smaller things: i couldnt really tell what they were laying on, so i assumed the red thing behind them was a couch and painted it more beneath them too. thats really all i can add, practicing some perspective and being bolder with your values is the main thing. hope this helps :3 for some reason artwod trimmed my paintover really weirdly so i had to cut the top off
