thank you guys for the comments.
ralph,
you're right, i don't like the mud effect either. it was my first time to use pastels (weathering pastels from gunze sangyo) and i made the mistake of not trying it out on a scrap piece first. i was surprised with the effect but i was too scared to clean it up. about thespare links, i really didn't know they were supposed to be in any specific position. thanks for pointing it out. with the regard to the figs, i definitely need lots more practice. thanks again!
charles,
i had a problem with the tank commander (actually many problems). it was my first crack at painting a figure and i had to glue the head back on several times. it was only when i finally took the pics that i noticed the neck thing. there's really no excuse for that one. i promiseto do better next time.
P.S.
i never thought non-filipinos would be reading this forum. thanks for taking the time to post your advice.
