Here's your choice of 2 pngs and a jpg to use and the story and how I made them and why I think the Gimp JPG works best!
This png was made in #inkscape
I used Char font and added two layers of Flame and a Black Outline then exported to Gimp for a final crop. Its okay for twitter but ... lacks. I think its loud but not quite strong or bold enough despite the red?
So I tired again in #gimp with the same font but stronger reds and the Comics filter ... nope still not the best and for some reason the letters are clearer at a smaller size though they seem clearer in the Chrome / Blogger browser then they did as icons in my Pictures folder? And now its too dark!
This is Verdana Bold with the same colors and filter
The lesson ? Resist the temptation to combine an ornament / fancy font with filters. Start with something plain and bold !
It may be I'm misjudging these and you prefer the 2 pngs?
