Do you need all that empty space? No you don't. Heck, you could remove all the first images and replace them with the last images. You could also paste in the concept (add name of artist too). At any rate - use yer pixels, just like you would in a UWV map. Also, why are the image borders blueish grey and the text yellow?
couple things i'm really curious about on your models. the girl for instance, why did you give her face such a small area on the texture map? spaces for faces(ha) tend to get more room than what you alloted. i understand you may be thinking bout texel density....but a good face can sell a model...so give her more pixels…
