you shudnt be afraid nissan, you shud experiment, and just try things, and if u are afraid to lose wat u have done, make a new layer, or copy and paste wat u want into a new layer, and therefore if u dont like wat u did, delete the layer, or hide it, but u have to try and do more mods. Also if you are unsure how to do something, then ask us, thats why we are here too, we can help...maybe next time you are going to post a finished chop of urs, post it in the WIP section and see if we can help point out anything that needs attention, and u can fix it before u post it, anyway some helpful advice to take on in ur next chop
