that last sketch - really something . Possibly, this one could feed into your final piece ?
I think this one looks really tortured! I like it but its totally copied (except for the mantis legs)from Gustave Dores woodcut of Arachne so I can't really claim it as my own work for the final piece :(
well, inspiration, that's how they call it now , or influence. If you were to go for something like this, it's always possible to do a variation of it. or use it as one of the 'components' while building your pose. But I like the new ideas you posted too! :]
