There is one major flaw in this piece, which is the far leg of the satyr. It's missing a segment, which looks strange even without the comparison of the other leg, but even more so with it. The line you currently have with the leg is good for moving the eye around the page, so keep that in mind if and when you add the appropriate section to the leg. Also, the upper portion of that leg, near the arm, is simultaneously in front and behind the arm. adding some fur in front of the arm will fix that easily. These are the only major flaws though, and I feel the image is extremely successful otherwise. Great job!
(also, I apologize for posting this in the normal comments first. I don't critique on DA often, and didn't know I needed to click the "Write a crit" button)
Same as the first critique. The left leg is bent opposite that the joint is supposed to go. The right leg looks great. I understand what pose you wanted to achieve, but it's hard to get that pose with an animal leg. And I don't have any ideas to fill in that area with his leg, because his leg wouldn't be able to bend like that. Only the hip... I You could re-position the leg and try adding another object in that corner to balance. Love to see more of your work though! That is the only thing that catches my eye, everything else is gorgeous! The women are gorgeous, and the color is amazing! I love the oranges and blues are reds. It's very vibrant, but dark as well. The texture and lighting are used well too!
I adore the piece, In fact, one of my D&D characters used this as a base for his appearance... but i disagree with your comment about the nymphs eyes looking stunned, if anything they almost look lifeless or dead, they look as if they havent moved in a while, and the way they are drawn look forced or posed, although this is only my opinion, and in my personal opinion i dont even mind that, it adds (For me) a darkness to the beauty, one of the mindset that beauty and life dont last forever so take your chances while you have them.
Very nice work, great use of the contrasting colors going from bottom to top, and the shadowing makes me feel like I am in the dark forest with them. razwit has already pointed out the limb problems, but otherwise a very fine work.
BTW... your satyr has Brad Pitt's facial features.
