Okay - I hope you folks can help me out here.
Someone recently commissioned me to do some artwork for their sister's birthday of some insects for her. Their sister is an entomology major and has a fondness for dog day cicadas.
This is not my usual subject matter and want to make sure this looks like a dog day cicada and that I haven't drawn something so off that it will look glaringly wrong to someone who knows the material. I am working off of references but a second opinion is always helpful.
So that said, any feedback anyone can give me on this could be appreciated. This isn't the finished piece but wanted to make sure that so far this is looking alright.

Thank you for your time. Any and all help is greatly appreciated.
