I do like to the look of that scheme, also the look of the tank with out the skirts. I might have to look this one up and add it to my collection. Good luck on the paint scheme, and can’t wait to see it.
Then i dont think you’re looking in the right place for oils… I dont think you could effectively recreate this look without oils. Most artist’s oils are like $5-8 per tube that will last you years. And you really only need 3 or 4 colors to be able to do most effects. Just get some black, white, raw umber and burnt umber and you’ll be set. Or get one of those variety boxes with the smaller tubes… Its definitely worth the investment.
Last week I got a 24 pack of oils at Hobby Lobby for about $11 after a 40% off coupon. The tubes are smaller, but it will take me 10 years to use them up. It was the ArtCreation Expression Oil Color Set. They have been working great so far as washes and on a 1/35 figure. They will have another 40% off coupon in Sunday’s paper or on their website next week.
