I like the contrast of the yellows and the greys. Also, great use of alignment and proximity between the text and the images to make them appear connected but not rigid. I like this newsletter layout a lot.
The emphasis the paintbrush creates helps to make a visual connection with the content of the article. The contrast the painting hand brings to the otherwise boring design is a simple element but it really impacts the design.
I use this software Adobe Illustrator to make a logo or large graphic such as hockey logo and floor ads. It can expand small vector to larger size. Vector means to prevent the images from getting blurred and the quality stays the same.
