The whole title for this is, "Rainbow Crash Into Dr Whooves & His Beautiful Tardis." But DeviantART didn't want a lengthy title so it's just "Rainbow Crash."
I wanted to do a mashup and who better to mash MLP with than Dr Who... or Dr Whooves... or Time Turner... whichever name you want to go with. The POLICE BOX PUBLIC CALL text at the top was painstakingly time consuming. I also did my best to make Rainbow Dash's mane and tail to have different layers/shades to look like a "rainbow." If you download it, you'll see the full detail.
This one took roughly 3ish hours to carve. Now it's time for me to crash before tackling one of the final three designs...
