about the gundam one..
picture not sharp enough...
need to invest more on lightings
hehe

other than that...u got lots of room to improve
keep posting

nah...not external flash
just some proper lighting would be nice

if u use flash only, u can see a harsh shadow behind the subject
but u couple it with a few light/soft light/diffuse...u can get a soft shadows/bright background/etc
anyhow..it still depends on how u like the background to be...

like u, i also experimenting on lighting position
sama sama belajar

btw, my lighting involves some table lamp, white paper/plastic cup as diffuser, card board as background
no $$$ mah....
