Sniz, I think if you are upfront and honest to your customers, they'll understand this.
I have a list of waiting people aswell, and last week I was feeling the pressure, and this week I've come to the conclusion that if I'm going to stress myself out about it, I'm only going to end up nowhere, be in the wrong frame of mind, and rush and ruin the results. I don't want to end up not enjoying it if I can't put my 100% into it. (bad ref photos don't help though I know
Looking forward to seeing more work of yours, when you are ready of course
