So, a few weeks later than expected (oh no, wait, make that months....uh no, no, my bad - make that years :/ ) finally got round to getting my side-art printed and installed. Also got the T-molding installed, so exciting to have a project envisaged in 2013 finally coming together!
In the end, I went for an unobtrusive sideart design (black and white and not too prominent, almost looks abstract if you don't focus on it) as the main features of this cab turned out to be the dynamic marquee display and controls display. The way these work tie the game's colour schemes together, thus presenting the front of the cab in the game's colours. Thus, I had to keep the control panel and sideart quite neutral so as not to clash with all the possibilities. Kept it black and white top keep it colour neutral. Very happy with the sideart finish and was easier than I thought it was going to be. The t-molding is also super dark green, so this also helps with the neutrality of the 'bright work'
