hi T2B not sure if this technique would help you taking these type of pictures with the glass been curved, as the glass reflects light back up the lens the closer you can get to it the less light is reflected back, if I'm taking a pic through glass i get as close as i can if i can touch the glass i put the lens touching it as it then becomes part of the lens its self and stops it reflecting back. don't use a flash and if the camera has a macro setting try using this as you are more of a 1:1 ratio for picking close detail up, you could try having the light source ( window or a light ) in front of you so the light comes through it and not reflect of it from behind you but not so bright it washes the colour out and turns it white, if it does go a bright white you could look at altering the white balance (wb) settings. sorry if this seems like a lecture but i don't find it easy trying to put what i know into words, but i find what you have done with this kit amazing and i hope this helps you get the picture you want to show how good it is.
