So... a good friend growing up asked me twice via text to paint him something. He had specific suggestions for what he wanted, trash polka style. I had no idea what that was. I googled it. and told him it was not my cup of tea. he said paint me an original with baphomet. he will pay me 400$ I said ok. I took pictures of my progress and sent them to him during the process. I even brought the painting to him unfinished and asked him what i should add, change remove... etc. Every pic of the painting i sent him. he said "amazing" at no time since the original texts where he said "Ill pay you 400" did he bring up money. i sent him a text saying, " you can pay me whatever you think is fair and gave him my paypal account. He said we can talk about it after its finished. I finished the painting drove two hours to give it to him. He never brought up payment. It has been over 2 months and he does not bring up the painting or payment. How do i proceed without damaging the friendship?
