Me too. (Naturally we want everyone to love our art, designs, illustrations unconditionally...!)
So what strategies have I developed for dealing with this?
You definitely feel rejected if your work is rejected - as really it is a little bit of you.
But you have to just carry on - keep trying.
Rework the designs or try a different combination and send them off again to somewhere else.
I also think reading between the lines is a skill worth developing. I get feedback like
'your work is very creative' followed by something like: but it's not appropriate for our portfolio at present -
And that's the helpful ones!! - I tell myself - ALL feedback is useful - even the straight negative feedback! Just turn the comments round - translate - interpret - dissect
I have interpreted it as this:
Very = too
Creative = all over the place
Which, joined up with not what we want says to me that I will have to develop a more 'together' style that has more clarity and says 'these designs are clearly all by Annie B' - a kind of signature.
(I tried to embed one of your videos here Chris - but it didn't happen, so here's one of the photographs from your lovely gentle blog)
And I suppose I have to admit it tells me I do really know what is required for my artwork to develop appropriately after all. No excuses then!
A bit of constructively critical self-questioning and a long hard look at the evidence will help you to develop as a creative person.
1 Send some work off
2 Expect rejection
3 Look at it as constructive feedback
4 Be honest with yourself
5 Do some more work
6 Go back to number 1...
