Well for your first one....
Not bad for your first attempt.... And for you to make it better.... Perhaps a little more detail for your model.... Stuff like eyebrows a mouth or nose.. Basic Facial features.. And maybe a lttle smoother lines some of them are slightly rough like in the arms... some sort of background music would not hurt anything also... But off of effort alone and for your fist try I can easily give it a 5 out of ten just for effort and a fist try... All in all not bad
