[Idi Amin]

let your forms run off the page, and leave a little more negative space over your subject to mantain balance. also placing your subject off-center is good, but it needs to either be more subtle, or more dramatic.

you have a good subject but your placement and composition really bring this piece down.

this could be good, but you need to focus less on your media, and make your final work look a little more intentional. if the media was your intended focus, then put it to more of a dramatic use, because there is nothing subtle here.

all in all you have a direction, but it seems a little under developed and that really kills what you are doing here
