This is done wonderfully! The colors all mesh well together, and the perspective is perfect. I can really sense the depth, it looks like it could be a real snapshot.
The only thing I see that could use some work are Kirby's feet. The back foot looks weird with the motion blur on the top. Usually when the front foot is going up, the back foot is going back. To me it looks like he is going to bring his back foot forward to meet the front. Maybe that was intentional as he is approaching a jump, but I feel it would have looked better with the motion blur on the back foot on the bottom. Or the motion blur on the front foot on the top.
Other than that it looks perfect! The grass looks so good I feel like I wanna lay around in it!
This is a pretty nice piece. I'm not sure which Kirby game exactly it's based off of, but I would guess Kirby 3. If that's the case I regard it even more highly as it captures that games softer style art exceptionally well. Once my eyes drift away from the intended focus on Kirby I notice lots of nice extra details, such as the grass textures, and the sparkles coming off the birds. The atmospheric fade to blue in the background is nice, as is the white foggy looking borders that draw your attention back to the center of the work. The only thing I consider a distraction with this is the motion blur on Kirby's feet and hands. I'm not sure exactly about it doesn't work to me, but it's the only thing I would even identify as a flaw. I'm too busy admiring the rest to really care about the specifics anyway. Again, great work on this one.
The texture in this one is amazing! I literally FEEL it! And the color pallid is perfect it actually reminds me of cake frosting which is perfect for the subject matter. The blur and the way the backdrop scenery looks (gives a sense of real depth) shows the 'movement' in the work and adds to the over all mood. It's nice that the Kirby and the birds are so bright, makes them pop! Really freakin sweet one you got here!
