I know this post is a bit lame but since after I joined some forums, it really change my mind about gunpla customization. I used to think that straight build will be the best and forget about the word customization. As long as I clear all nub marks and all paint went smooth on the surface, it should be perfect. I think I start to paint my gunpla about 2 to 3 years ago and started to realize customization is something fun to do but there is always one problem that I face (or some amateur modeler) is from where the customization start, what are the steps and how to get those steps done (considering on skill, tools and material as well). What I experience is whenever I try to do start it without a plan, I will always end up with lot of mistakes and the worse part will be the result turns out negatively. I always think of creating my own concept for every gunpla kit that I’m going to build but this isn’t easy for me to get there (especially when I restricted from my wallet, space and time). I always think that if I can get those tools and material, I can be as perfect as other but the fact is I can’t even master the tools and material yet, how can I get there? So, my solution for myself now will be take more time to understand and learn what I got before I can get to another level. The reason I wrote this post is simple, the trend of customizing kit is growing no matter in OC or PC. It is great to see lot of masterpiece out there so the amateur (like me) can study more and expose to different concept.
The first step for customization will be the concept before anything start, maybe I should explain what is OC and PC base on my own definition in gunpla. Customizing gunpla base on the gundam original concept (OC) is basically improving the gunpla model kit in terms of detail up, improving joint or proportion, adding more panel line, pla-plate, re-paint, casting new part (such as adding armor or weapon) and adding customize decal that related back to the original gundam concept but the overall customization done on the kit will still remain the original concept of the gunpla (gundam).One of the most important thing to remain the gunpla customization in OC should be the color scheme. Whenever the gunpla re-paint, majority of the color selections should be similar to original color scheme. Converting gunpla kit to another gunpla such using MG Freedom inner frame and transform it in to Justice to make a Justice MG Format can also be categorize in OC in my definition. As long as the end result is what we can find in gundam series, it should categorize in OC. It might feel boring on building and customizing a gunpla kit base on the gundam original concept but sometime, OC can be better than PC and it can be harder to get it done especially when improving some old MG to match up the latest MG.
Scratch build or using conversion part should also consider in OC as long the end result is what we can find in gundam series.
