At last my 1st mech finished, tough it's not 100% pure idea, I took lots part from other mech as reference:
Head: Eva-01 (Evangelion)
Core: Gundam Exia (Gundam 00)
Legs: 03 Rayleonard Aaliyah (Armored Core)
Shoulder armor: Neue Ziel (Gundam 0083 "Stardust Memories")
Rifle: 03 Rayleonard Aaliyah (Armored Core)
Basic Shape: Hydra Gundam (Gundam Wing Dual Story: G-Unit)
Ha... it's looks like a chimera-bot...
The basic concept is a monstrous mech, so i take head from eva - 01, combined with my fave mech from armored core- 03 Aaliyah, and my fave gundam Hydra. then so be it...
