You're probably less than half way complete
working on the front design, but it really is heading in a good direction...
criticism is good - without it, you may not know how to make a better product. At least now you may be seeing some of the comments that could be doing your future kit sales "bad". While it's still in the production process, you will probably make several more adjustments to build your design much more unique from anything else already available and more desirable.
