Added some new pledge rewards (Patreon)

I added some new rewards, used to have them but removed them when I lost almost all my patrons a while ago, but thanks to a suggestion from a friend I'm adding them again, but now a bit better imo, but I'll let you decide, please tell me what you think and what rewards I can add

Sketch tier - You get a sketch commission every month for 10$, 5$ cheaper then my normal commission price

Colored sketch tier -  You get a fully colored sketch commission every month for 20$, 5$ cheaper then my normal commission price 

Colored picture tier -  You get a fully colored picture commission every month for 40$, 14$ cheaper then my normal commission price  

I hope some of you will consider then new tiers, and I hope you like them
