Hey mate, only just saw your post. Been a very busy period and haven't had the chance to log here or either Flickr to add more photos. Now, taking your queries one at a time.
I did try using a soft box but what ended up happening was the soft box covering my subject thus getting it under exposed. see here: https://www.flickr.com/photos/antonispapavasiliou/9328535364/
Unfortunately since then i moved to another house with less of a mess in the garden which means i don't get to see as many bugs anymore unless i venture towards the country a bit which would scare the old people around my area ( a slow moving guy on his knees for hours and hours trying to shoot bugs)
I also see what you mean by the flash "affecting" the colours a bit but i'll be honest i kinda like it ! I'd prefer a more natural feel to it but i guess giving them a "model" look sometimes gives a different feel to the photos.
As for Flickr am not sure how much safer it is from Facebook ( i know FB owns any photos that are uploaded there) but i like the interface you get with Flickr. Strictly photography and no other annoyances… As for a copyright symbol and logo just make a template using any software you have and then layer it onto of your images ! That's how i do it !!
P.s. Thumbs up on your photos on Flickr.
Thanks so much for your reply and positive comments, I’m sorry it’s taken me so long to reply too, I’ve also just moved house so feeling your pain!!
I found this little fella on the window in the kitchen about 2 weeks back, I really see the benefit that the L version (with IS) will afford me over my current non L 100mm lens, another expense LOL
