I'm a long-time lego builder, since I was 4. I particularly focus on space creations. I generally prefer to work with the classic space colors, plus dark grey and black. Generally I try to cover this as saying 'classic space/unitron' colors.
Many of my creations I design and build can be purchased. The purpose for offering these is two-fold: to provide good custom space sets to interested people; and to help fund projects/donations I do/make to my local animal shelter rabbits/Wisconsin House Rabbit Society. Part of every set sold is either donated or put into a projects fund for rabbits at Waukesha Humane Society.
To purchase these you can visit my Bricklink store here:
On the left-hand side of the page, go under "Sets" and select the category you want to view.
