Lyraina's sketchbook

[Blewzen]

I think those designs are a good start, just i would say they would look better if you stylize the figures, try to make them have 7-8 heads tall and make them thinner legs i know some of the outfits supose to have thick legs but do it with the rest. Use existing concepts as reference you won't necessary rip them off but try to see how they design, see the shapes they use and make it yourself.
Im not so good with sci fi stuff but this is what i do when im gonna design something :0, keep it up!
