Glad it was of use to you, even if only for learning with.
Clipping issues is VERY common in DOA modding, since the weighting is different on every outfit mesh and nude body mesh, it comes down to you having to ask yourself "am I ok with how far its come?" and eventually telling yourself "yes".
Don't worry too much about it, I often go back and rework some of my Mods months later when I figure more out, but not saying you have to, my fixes are minor and I'm just OCD like that.
I would suggest you make a .zip or .rar file for it, since people won't have to DL 4 files separately and you can keep track of your Mod collection easier.
Once more great work and hope to see more from you in the future!
