I managed to complete the pen, magnifying glass and one of the lighting tutorials so far - Yay! I'm pretty happy with how I'm doing at the moment, but clearly it's going to take some time to get comfortable with the software.
(With the pen you may notice there's a hole!!! I did actually create the whole pen with the ring and handle, but somehow deleted that section along the line - quite upsetting as it was looking promising! I decided to continue adding texture, lighting and rendering the pen to still give me an idea of the finished piece. Once I've caught up to speed with the other tutorials I'll create the pen again.)
