First I want to say hello.

This is my first post... I have lurked from a distance for awhile, but recently decided to start posting my work for suggestions.
I mainly do graphic design work, but I have been a fan of pixel art some time now, and I usually dabble in it for fun in my spare time.
This is my first professional piece for a mobile and web company.
This first image is the original logo I designed for them

And below is the isometric pixel art version. I kept it simple on purpose, and don't want too many colors going on, but I think its boring.
I also want to try and make a half size and even quarter size version, but I don't know how to make it smaller without basically starting over.


I used Photoshop and illustrator for the main work, and then used that as a "background template" and plotted the pixels in Pixen.
Any suggestions would be great. I have learned a lot reading everyone's post on this forum.
Thanks - Popkiltr
