Oh, Spike. You and your humor.
Be careful with the SVG, there are A LOT of nodes!
Feel free to use, you don't have to ask or credit me if you don't want to.
As for the background, it was easier to create than it looks (I can explain if you're interested).
SVG Here: sta.sh/02butcxjdgis
Update: Fixed some incorrect miter angles.
Update 2: Redid most of Twilight's strokes to use Pattern on Path and Mutual Clipping. Please note that Ponyscape is not practical for this because it creates thousands of nodes and that is something I want to avoid as the image already has a very high node count (due to the background).
Update 3: mewtwo-EX's suggestion.
Update 4: more fixes.
Update "holy sh*t another one": recolored due to release of Color Guide 2.2; fixes on Spike, node reduction
If you use portions or all of this vector in other vector artworks, you MUST provide the link to your source vector for any of your artwork that includes my work. (what?)
