Hey dude thanks for stopping by my book.
Really dig what's happening here. Pencils are coming along great.
Think your critters look great - very believable - but they feel too awkwardly stiff. Think this might be a by-product of drawing them in profile, but you might solve some of it you just let go of your pencil - don't worry about being tight when you start off, just loosely find the right pose and musculature. Remember opposing curves as you place both your gestural marks and the masses.
Not sure if that was of any help, if not then just ignore it all flat out.
Overall kick ass book, 5* man.
