Interesting thoughts overal. I share the opinion, that a miniature painting hobby needs good concentration, attention to detail, it helps me, for axample, to improve my lack of patience, and develop accuracy. Long gone times when I used to drybrush, I read, explored the subject, and watched artists work. I began experimenting with paints, primers, washes, flocks.. Such deep hobby it is.. And each time, when I started a mini, I had more confidence, that it will come up well. Though still, I have a normal feeling, that I'm useless, untill the first wash is applied ^-^
I don't own many miniatures, I restrict myself to buy more then 1-2 minis per month, now I have certain collector's goals, and get the minis I really need to fill my unit list. I won't buy a mini I wouldn't like, and unfortunatelly, time stopped for me at 3025 era.
At that point, commission painting gave me the oportunity to get hold of various mechs models. Ones I hated, ones I loved. And it's also a chance to try out a paintscheme I would never used on my minis. You put yourself time limits, that let you think on quicker and better techniques to make a good and not overdone piece.
Can't say I like cutting metal or assembly stages. I hate cleaning mold imperfections. Sometimes it's too much for me to be calm. You can spend a day, cutting away and sanding flash, only to see an overlooked damn mold line after priming. But, even if this process seems boring, I got used to it, and somehow learned to enjoy it.
I'm always in a search for a perfect painting solution, it's great, that Camospecs has such nice artists to learn from. I relax, launch some UFO sci fi on youtube, put some acrilics on the palette and get the mech done for battle 8)
