This awesome piece is from sparkythechu - it's one of the first solid references I ever had for Lucas, it helped me settle on my striping pattern when I wasn't exactly sure how it should look (between this and Psychic Barrage, those two together cemented it...) and it's also the first rendition of Lucas that I got airbrushed onto a t-shirt - if you see me walking around Anthrocon and I'm NOT in suit, this is probably the version you'll be seeing.
How I missed uploading this is beyond me. My bad on that 'chu!
