Now you're asking me something I'm not sure of.A little explanation may be needed l am retired and l do have a lot of free time,l never think of the time l put in its something l enjoy doing and the time passes so fast and l usually work on more than one model at a time,and on average l put in 4 hours a day,l think at a guess it would be around 25 hours,and l must say my standard is not that high,l paint to the point that I'm happy with, there are a lot of other talented painters on this form that leave me for dead.Mate just paint and enjoy and if you love what you do you will find time doesn't matter.(P.S hope l didn't rave on to much)
Cheers Jim
