Gundam Barbatos 6th Form HG 1/144

Hello guys, I am posting my first gunpla. I am new to gunpla building, and this is my first gunpla kit.
I was so happy when I built it. It feels like an achievement for me.
This is a High Grade (HG) Gundam Barbatos 6th form from the Iron Blooded Orphans series of Mobile Suit Gundam.
This Gundam was used by the main character Mikazuki..
I bought this HG Gundam because my friend who is a fan and a gunpla builder taught me that I can buy a HG kit, because I am a beginner.. Take a look at my own build gunpla..

as you can see, the panel lining was a bit messy, I still didn't paint it, but I am planning to.
the articulation of this kit is good, it also has an inner frame,.

This gunpla is good for me, I am satisfied for this, you can give me an advice on how to be agood gunpla builder. And also, you can suggest what gunpla should I buy next.

thanks..
