Some works seems overtopazzed, other works' colors are washed away which kills the composition and make the tags novice despite being good looking. well not bad for a come back but you can do better. cheers
Your best is the 4th and 5th this time .. Not like this is your best cuz you did much better before .. Anyway not bad at all .. i like them all honestly.
Your renders look me directly xD First one's background is simple. Render is too big. Third one look blured. Fourth one's background doesn't match with render. Fifth one need more depth.
