Well, you've come to the right place to find out your salts worth.
It takes time for something to appeal to the masses. Look at Nike or Apple to start. Your colors are a little overboard, but hey, good things take time.
You need to take what most here dish out as sound advice.... as just being jealous. They all know ya hafta start somewhere. As mentioned, walldogging and painting murals on buildings are nothing more than graffiti at it's finest. All letters are is a series of straight strokes either up & down, left & right with curves going in all kindsa directions. Put 'em all together and what've ya got ?? Bippity-bobbity-boo..... commonly known as design/logos, graphics/lettering. Most of your inner cities today are hiring these graffiti artists to paint up the town, so..... you're probably onto something possibly very big and ahead of the rest of the pack here. Being a jockey should tell ya something about that.
Keep at it and your creation will eventually get there.
