Nevermind, I guess. I suppose I'm seeing things in a different perspective. Thanks for the feedback (:
Actually I've seen quite a bit of space helmets that are generally melded into this form. Not all of them are a complete round shape, I've seen more like this rather than the general round ones.
You're letting the shape of the frame dictate the size and shape of the subject matter--spacehelmets are generally round but this one's been crunched to fit a square canvas.
Of course. I hope you'll keep experimenting.
