Even if it is suppoed to be above me, i'll rate Randomizer's, since i haven't yet, and i already rated the one from above.
7.5/10, and my complains goes to:
He is just, standing there, with a generic idle pose, that is fine for a reference image for when you're gonna do some other art with the same entity so you have a clearer idea of how he looks like, with a generic reference image, but, well, it is there, usually more dynamic poses spices images ALOT more, and makes them more fun to look at. And, where is he exactly? He is just in the middle of some random grass lands, because, sure?

All this image is missing, is spice.
If these were fixed, it would've been really cool. Easy A+ it would be.
Oh yeah and that's Metal Slug, i have watched some videos, even if i haven't played, but what tells me that it is in-fact Metal Slug, is the gif below your profile or something.
