Nice feedback, I can get behind most of this.

It is quite possible to break the ingame economy tho, paintings are even more valuable than they used to be.
The interesting thing you can do with them is stuff all the paintings in a pouch, sell that pouch to a vendor and clean out their inventory, then you can pickpocket the pouch back because the game only registers the weight and value of the pouch, not its content. Then you can sell the pouch back to the vendor once he restocks, and if you are going to eventually murder the vendor for XP you can sell this pouch worth their full inventory three times to every vendor you meet. You can do the math on what tat amounts to in gold. Especially since you can "buy" all the stuff you want without using gold.
