Technically you could be a lot better
for example some of your blending is a bit off and it looks like the image dont belong there...
however your creative and ideas for your graphics are very nice
i like the obito one the most - but wish that you were technically better because you couldve made it blend better, fixed the lighting a bit and given it a LOT more depth!
also you need to start holding the 'shift' button while u resize things - or change the sizes (proportions too) of your canvas because you've stretched 1 or 2 of the renders uve been using xD
not bad but a lot to improve on
