Awesome picture Vlad
Patchin, what camera body are you using this lens on?
I do not have any personal experience with the Tamron 60 mm macro. Speaking solely from a "focal length" point of view however, 60 mm is a very capable FL to work with. Granted, it will not provide you the same magnification as a 90, 100, or 105 mm, you can still do plenty with 60 mm. And if you can't get close enough, cropping is a solution for some.
If you have never tried macro photography, I might suggest keeping your new lens for a little bit, and shooting around with it. See if macro photography is really something you would want to invest more in. Some people may advise otherwise -and just ditch the 60 mm, and leap for something in the 90-105 range, and that is fine too. It is really your call. Though, I might also add that you don't have much to lose by keeping it for a little bit, and giving it a little play time.
Also, consider what you may be using the lens for other than macro photography. "Macro" lenses can be used for everyday picture taking, simply treat them as a regular prime lens. Personally, I don't use my macro for anything but macro work because 100 mm is too long a FL for me. I'd rather use the 60 mm FL for everyday shooting. Again, that is me.
Just something to consider.
