My first image review

Hi all,
I'm new to the forum and also new to DSLR's, in fact I have very little SLR experience at all unless you count the time I owned a Pentax P30n for about 2 years before loaning it to a mate never seeing either of them again.
Yeah I can laugh about it now but that was 12 years ago.
Here are some photos I have taken over the last few weeks since getting my new DSLR.
I would appreciate your thoughts
