Book questions (Patreon)

Hi folks, I'd like to get your opinion on a couple of printing options for the book I'm working on.

I think it's going to come in at around 72 pages, full colour. The print options are size and whether or not I go for hardback or soft back.

Something around A5 size, soft back I can probably sell for £12 to £15 I think

Hardback, somewhere between A5 and A4 would be more like £18 to £20. 

Post and packaging on top of that obviously. What do you think of those prices for a book of the Weird Field World stuff? I've looked at other artists selling books of their work (without background text etc) and the vary but are often over £20 for a soft back book, sometimes £25, and even up to £50 (Karl Kopinski).

Any thoughts welcome.
