ivanlyw

i worked on this during the holidays and i really had fun with this i was wondering if i could get feedback on the weapon please let me know. i am very weak at hard surface and if there are anyone who could give me pointers on the weapon that would be great! 1 problem I noticed is the sword being too thick because i have multiple pieces stacked on it but it ends up having a very blunt edge. Is there a way to stack them up but keep the edges of the blade sharp? i tried with the move tool but it keeps deforming the blade.
