Hi Caroline have had a quick look at your shots for images taken on a compact type camera with a fix lens they are what’s to be expected, the first one of the bug is the better of the two although to be honest with you the composition could be better if you had got lower and in front of him, the second one of the butterfly seems to have a lot of noise and not in focus. As for your question regarding getting the Canon 60d with the 100mm macro my personal view is get it you will not regret it, you will find it a steep learning curb and you will at some stage want off camera flash or a dedicated macro flash so you can increase your DOF as with a macro lens at 1 to 1 it will require a lot of light or high F-stop like F/2.8 to F5.6 and even then not all of the subject will be in focus, to achieve that is when the flash comes into the frame and you can increase your DOF between F/14 to F/22. I will leave a link below to my flickr page so you can view the different images with and without flash, just click on my 90mm Tamron folder. There are also two links to someone using the Canon 60d and 100mm macro lens so you can see the quality that combo will produce, if you search flickr for Canon 60d macro it will bring other images up.
