Hi Shane,it is a challenging scheme,and I am pretty good with my Airbrush,through trail and error but this one will be difficult.
I learned a very useful tool is a lead pencil,not only for the outlining of details but to ghost in the lines between the camo colors and shapes,this helped me a great deal to follow the pattern and to keep the color straight,marking each area with a letter.
It might be this weekend before I try this scheme,me and Ken looked through a hundred before He found this one on the Australian site. If I may be of some assistance please let me know. I was fortunate on my first to have a real pro guide me through it twice! Their really are some very skilled guys on our forum,thankfully,I;m not one but,i have done five now and picked up some basic skills.
Good luck,if possible try for a double action airbrush,better control. All the best.
