Here's another Gem Fusion key chain design. This time of Rainbow Quartz.
She's actually the first one I started on, but I was having a lot of trouble drawing the day I began the sketch (I was super stressed about the general prospect of having a convention booth). Wasn't able to draw the day after either. It wasn't until I began on and then later finished the Sugilite design that I finally got into the groove of things.
The lines on this one are there because since Rainbow Quartz was introduced in a segment that had odd lighting, rather than try to guess what her normal skin and hair colour might be, I decided to simply use the colour scheme she was displayed with. Meaning there's more colours on her than on any of the other designs. Her hair in particular, which it why the lines are there--to indicate the separation of different colours. I used about five in total; a pink, an orange, two shades of yellow and a blue.
Sardonyx is finished as well (sketched, inked and coloured) but I won't be posting her until her episode is released.

As per usual (but for some reason must be specified on this site) critique is welcomed, encouraged and appreciated.
