The apple's shape looks a little strange, and the football player's left hand is really tiny. Not sure whats up with that last one. I like the effects you made in #4 and #3. The rest of them are well done as well, just those little quirks I mentioned. The last one just seemed really strange to me, I don't really care for the pose or expression, and the hand needs a lot of work.
thanks mate, i will try to work on that stuff (proportions...etc) the last one is just a vexel of a pic of alexandr lukashenko the forth one is a painting i did with the default soft brushes.
